Abstract

Drinking water supplies located along the coast of Indonesia face susceptibility to saltwater pollution due to seawater intrusion, including in the coastal area of Batang, Indonesia. Therefore, this study aims to determine the community’s ability to access water in the Batang coastal area following the seawater intrusion phenomenon. First, an interpolation in ArcGIS based on the electrical conductivity measurements of 40 wells was done to identify and visualize areas affected by seawater intrusion. Furthermore, we interviewed 116 respondents and employed the contingency valuation method to calculate and analyze the public willingness to pay (WTP) for improving drinking water sources contaminated with saltwater due to seawater intrusion. The results showed that the groundwater near the coast was already contaminated with salt water, with the highest electrical conductivity value reaching 3999 μmhos/cm. Furthermore, the economic valuation analysis results show that the expected WTP of the entire population for enhancing water quality is IDR 17,830 (~ 1.1€). The expected WTP of the population affected and not affected by the intrusion is IDR 31,150 (~ 2€) and IDR 14,800 (~ 0.9€), respectively. Compared with the minimum wage in Batang in 2022, i.e., IDR 2,132,535, the expected WTP for the entire population, the population affected, and not affected by the intrusion, were 0.84%, 1.46%, and 0.69%, respectively. This study offers valuable insights for future investigations and serves as a foundational reference for local governments and communities in their efforts to enhance water quality in natural ecosystems through more comprehensive and efficient strategies.
